Meanwhile "Engineering Leader" at Chrome argues that 2.4s to First Contentful Paint is fast: https://twitter.com/addyosmani/status/1678117107597471745?s=... Google's one (of many) heads has no idea what another (of many) heads says or does.

Whether 2.5s to LCP is fast or not depends on what your normal day to day experience is

The incentives to measure this and to interpret measurements are completely perversed.

Of course, when everything takes 8 seconds to load, 2.4 seconds is "fast" :)

Isn’t that tweet talking about 2.4s for Largest Contentful Paint? It mentions 0.9 for FCP being fast, which I agree is pretty reasonable.

Yep, and this also is referring to the P75 LCP. Notice how’s he referencing the field data from Page Speed Insights, which is reporting Core Web Vitals. Anytime these metrics are discussed it’s always the 75th percentile.

Funnily enough I clearly remember typing Largest Contentful Paint. But it turns out I typed First :) My point still stands. "The First Contentful Paint (FCP) metric measures the time from when the page starts loading to when any part of the page's content is rendered on the screen." [1] Unless your server is overwhelmed, and can't send back data fast enough, there's literally no way to call "1 second before anything…

He’s referring to the P75 from Chrome’s field data. Now, Reddit definitely could do more here and get that LCP at the same time as the FCP (eliminate load and render delay). But a big purpose for these metrics is to make the web more accessible/usable, and the reality is most of the world doesn’t have iPhones or fast networks[1].

Indeed, most of the world doesn't have iPhone.

And yet these metrics literally optimize for Reddit's 109 Javascript files to render a page of text with images in 2.4 seconds. And they call it fast.

However you slice, dice, or interpret these metrcis, none of these shenanigans make it fast.

What these metrics and "75p" show is that modern web sucks for everyone, and they have to pretend that 2.4s to render a page is fast because everyone is even slower.

Or, to put in context: Reddit's servers serve that page in under 200 milliseconds. There's literally no justification in the world that make it ok to say "2.4 seconds to render that on screen is fast". None.

We started seeing reports about it in GSC early July, when over a single day all our scores turned to crap with no explanation. We are in the yellow, but the biggest culprits for blocking time are...Google Tag Manager, GAds (and Ganalytics where we still have it). So yeah, thanks Google, can't wait to lose on SEO due to your own products. And also, thanks for releasing this without the proper analysis tooling. ( http…

I for one commend Google's efforts to improve the web's chances of long-term survival by eliminating themselves and hopefully tracking in general.

Meh, with Googles resources they could do so much good. This is a drop in the bucket, compared to what they could be doing.

My company is scrambling to account for the changes here, and ultimately it will be users who suffer until we have the proper data available.

This should’ve been a standard that all major browsers have implemented and agreed to, before being rolled out generally.

Oh come on, it's not like their mission is to "do good" or even "don't be evil" any more.. it's to benefit shareholders.

They don't care if their web tendrils are a net positive or not
